The liquid crystal panel 37 includes the first substrate 32 including, for example, a gate line (not shown), a data line (not shown), and a pixel electrode, the second substrate 31 including, for example, a black matrix, color filters, and a common electrode and disposed to face the first substrate 32, a polarizer plate (not shown) disposed under the first substrate 32, and a polarizer plate (not shown) disposed above the second substrate 31. The color filter or the common electrode may be disposed on the first substrate 32 instead of being disposed on the second substrate 31, depending on the type of the liquid crystal panel 37. When an electrical signal is transmitted to the liquid crystal panel 37, an image is displayed on the liquid crystal panel 37. In the following description, for brevity of explanation, it will be assumed that a surface of the liquid crystal panel 37 on which an image is displayed is a first surface 37-1 and a surface of the liquid crystal panel 37 that is opposite the first surface 37-1 is a second surface 37-2.

The liquid crystal panel 37 includes the plate-shaped panels stacked therein and resting on the intermediate receiving container 100.

A gate driver IC 33 is integrated onto the first substrate 32 and connected to each gate line (not shown), and the flexible circuit board 35 is connected to each data line on the first substrate 32. In alternative embodiments, the gate driver IC 33 may be disposed on a flexible circuit board (not shown) connected to the first substrate 32 or to a separate printed circuit board (not shown) connected to the first substrate 32 through the flexible circuit board.

Various driving elements which apply a gate-driving signal to the gate driver IC 33, apply a data driving signal to the flexible printed circuit board 35 or process the gate-driving signal and the data driving signal may be mounted on the printed circuit board 34. In the following description, for brevity of explanation, it is assumed that a surface of the printed circuit board 34 that is on the same side of the printed circuit board 34 as the first surface 37-1 is of the liquid crystal panel 37 is a front surface 34-1, and a surface of the printed circuit board 34 that is opposite the front surface 34-1 is a rear surface 34-2.

The backlight assembly 10 includes a light guide plate (LGP) 300, a reflective sheet 400, optical sheets 200, a lower receiving container 500, an intermediate receiving container 100, a light source 353, and a flexible printed circuit board 351 for driving a light source. The LGP 300 may be made of a material with light-transmitting properties in order to efficiently guide light. In one exemplary embodiment, the LGP 300 may be made of acrylic resin such as polymethylmethacrylate (PMMA) or a material with a fixed refractive index, such as polycarbonate (PC).

Light which is incident on a side of the LGP 300 made of the above material has an angle of incidence that does not exceed a critical angle of the LGP 300. Thus, the light is delivered into the LGP 300. When light is incident on a top surface or a bottom surface of the LGP 300, it has an angle that exceeds the critical angle of the LGP 300, and does not enter the LGP 300. Thus, the light incident upon a side of the LGP 300 is uniformly transmitted within the LGP 300. In order to allow guided light to be directed upward, a diffusion pattern (not shown) may be formed on any one of the top surface and the bottom surface of the LGP 300.

When the diffusion pattern is formed on, for example, the bottom surface of the LGP 300, guided light may be output upward at an angle smaller than the critical angle.

At least one light source 353 is disposed at either side of the LGP 300 to emit light.

In the present embodiment, in order to achieve the desired slimness of an LCD, a point light source, such as an LED, may be used as the light source 353. However, the present invention does not exclude the use of a line light source, such as cold cathode fluorescent lamp (CCFL), an external electrode fluorescent lamp (EEFL), or the like. In the following description, however, for convenience, assume that the light source 353 is a point light source.

The light source 353 may be disposed at one side on the light source driving flexible printed circuit board 351. The flexible printed circuit board 351 may be electrically connected to an inverter (not shown) for supplying power to be supplied with power.

The reflective sheet 400 is disposed below the LGP 300 to upwardly reflect light emitted downward with respect to the LGP 300.

The reflective sheet 400 may be made of a reflective material, such as polyethylene terephthalate (PET), and may have one surface coated with a diffusion layer containing, for example, titanium dioxide.

The LGP 300, the light source 353 and the reflective sheet 400 are received in the lower receiving container 500.

One or more optical sheets 200 are disposed on the LGP 300 to diffuse and focus the light delivered from the LGP 300. The optical sheets 200 may include a diffusive sheet, a prism sheet, and a protective sheet. The diffusive sheet may be positioned between the LGP 300 and the prism sheet to disperse the light incident from the LGP 300, thereby preventing the light from partially concentrating. The prism sheet may be formed such that trigonal prisms are formed in a predetermined arrangement on one surface of the prism sheet. The prism sheet may focus the diffused light emitted from the diffusive sheet in a direction perpendicular to the liquid crystal panel 37. The protective sheet may be disposed on the prism sheet to protect a surface of the prism sheet or to enhance luminance uniformity of the light passing therethrough.

The upper receiving container 20 includes a window at its center, the window exposing the liquid crystal panel 37. The upper receiving container 20 and the lower receiving container 500 are coupled to each other, and the intermediate receiving container 100 is interposed therebetween.

The upper receiving container 20 and the lower receiving container 500 may be made of a metal having some rigidity, such as stainless steel.

Referring to FIGS. 1 through 3, the intermediate receiving container 100 according to an exemplary embodiment of the present invention includes a frame 120 and a printed circuit board mounting portion 1000 positioned on an exterior surface of one of sidewalls 121 of the frame 120.

The frame 120 may be a frame including an opening. For example, the frame 120 may have a rectangular shape with four sidewalls. Here, the frame 120 may include a panel resting portion 130, which is a ledge inwardly protruding from the sidewalls. The liquid crystal panel 37 rests on the panel resting portion 130. Specifically, the liquid crystal panel 37 rests on the top surface of the panel resting portion 130 and the optical sheets 200 contact the bottom surface of the liquid crystal panel 37, thereby preventing the optical sheets 200 from sliding or moving in the lower receiving container 500.

The printed circuit board mounting portion 1000 is positioned on an exterior surface of one sidewall 120 of the frame 120. Here, the printed circuit board mounting portion 1000 includes slide rails 1100 and 1200 into which the printed circuit board 34 is slidably inserted. Referring to FIG. 3, the slide rails 1100 and 1200 may be formed on one sidewall 121 of the frame 120 in pair to be spaced apart from each other by a predetermined distance P1. Accordingly, one side of the printed circuit board 34 and the opposite side thereof are slidably inserted into the slide rails 1100 and 1200, respectively, to then be supported.

Referring to FIGS. 1 through 3, the slide rails 1100 and 1200 include protrusions 1110 and 1120 protruding from one sidewall 121 of the frame 120 to an edge of the liquid crystal panel 37. In addition, the slide rails 1100 and 1200 include grooves 1120 and 1220 which are formed at one side of the respective protrusions 1110 and 1120 and into which the printed circuit board 34 is slidably inserted. The grooves 1120 and 1220 may extend from a sidewall 121 of the frame 120 to distal ends of the protrusions 1110 and 1120. The first and the second ends of the printed circuit board 34 may be slidably inserted into the grooves 1120 and 1220. In other words, the printed circuit board 34 may be mounted on the printed circuit board mounting portion 1000 in a sliding manner without the necessity of being assembled with the intermediate receiving container 100 using a separate fastening member, such as a screw. A length L3 of each of the grooves 1120 and 1220 may be substantially equal to a width (‘W1’ of FIG. 5A) of the printed circuit board 34. Accordingly, the printed circuit board 34 may be inserted into the grooves 1120 and 1220.

Referring to FIG. 4, when the printed circuit board 34 is slidably mounted on the printed circuit board mounting portion 1000, the printed circuit board 34 may be finally disposed on one side of the outer surface of the liquid crystal panel 37. In addition, the printed circuit board 34 may be mounted on the printed circuit board mounting portion 1000 such that the front surface 34-1 of the printed circuit board 34 and the first surface 37-1 of the liquid crystal panel 37 face the same direction. surface 34-1 or The printed circuit board 34 and the liquid crystal panel 37 may be disposed so as not to overlap each other.

In the present embodiment, the liquid crystal panel assembly 30 may be assembled in the following manner. First, the first and second ends of the printed circuit board 34 are slidably inserted into the grooves 1120 and 1220 of the slide rails 1100 and 1200, respectively, to be disposed at an exterior surface of the sidewall 121 of the frame 120. After the printed circuit board 34 is mounted on the printed circuit board mounting portion 1000, the flexible printed circuit board 35 connecting the printed circuit board 34 and the liquid crystal panel 37 is bent to place the liquid crystal panel 37 on the panel resting portion 130. This way, the liquid crystal panel assembly 30 is received in the intermediate receiving container 100.

Referring to FIGS. 5A and 5B, when the first and second ends of the printed circuit board 34 are mounted on the printed circuit board mounting portion 1000, the liquid crystal panel 37, the flexible printed circuit board 35 and the printed circuit board 34 generally form a U-shaped configuration.

The flexible printed circuit board 35 may have a first end 35-1 and a second end 35-2. In an exemplary embodiment, the first end 35-1 may be connected to the liquid crystal panel 37 and the second end 35-2 may be connected to the printed circuit board 34. Meanwhile, a width W1 of one side of the printed circuit board 34 may be substantially equal to the length L1 of each of the grooves 1120 and 1220.

Referring to FIGS. 6A and 6B, the slide rail 1100 includes a securing portion 1130 formed on a sliding plane 1122 of the groove 1120. The securing portion 1130 may be shaped of a protrusion protruding from the sliding plane 1122 of the groove 1120. The securing portion 1130 is received in a receiving part 38, which will be described below. Accordingly, the printed circuit board 34 is fixed in position after being inserted into the slide rail 1100.

Referring to FIG. 7, the receiving part 38 may be formed at one edge of the printed circuit board 34. The receiving part 38 may be a coupling hole penetrating through the edge of the printed circuit board 34 to be coupled to the securing portion 1130 printed circuit board 34. Alternatively, the securing portion 1130 may be a hook.

Referring to FIG. 8, the printed circuit board 34 slides along the sliding plane 1122 of the groove 1120 and continuously slides along the inclined plane of the securing portion 1130 until the securing portion 1130 is securely inserted into the coupling hole 38.

The intermediate receiving container 100 may be made of a molded material, for example, a plastic material. Therefore, the intermediate receiving container 100 is easily formed even if it has a complex structure. In particular, the protrusions 1110 and 1120 of the slide rails 1100 and 1200 extending from the one sidewall 121 of the frame 120 and the grooves 1120 and 1220 may be easily formed.

As described above, according to the present embodiment, the printed circuit board mounting portion 1000 and the intermediate receiving container 100 for mounting the printed circuit board 34 can be easily formed using a moldable material. In addition, since a space for fixedly mounting the printed circuit board 34 is secured, a separate processing time required for fastening the printed circuit board 34 using separate fastening members, for example, bolts and nuts, can be reduced in the manufacture of an LCD, thereby achieving miniaturization of the printed circuit board 34 and improving the integration density of the printed circuit board 34.

Next, a liquid crystal display according to another exemplary embodiment of the present invention will be described in detail with reference to FIGS. 9 through 13. FIG. 9 illustrates an exploded perspective view of another exemplary embodiment of a liquid crystal display (LCD) according to the present invention, FIG. 10 illustrates a circuit board mounting portion of the LCD shown in FIG. 9, FIG. 11 illustrates a cross-sectional view of the circuit board mounting portion of the LCD shown in FIG. 9, FIG. 12 illustrates an enlarged view of a “C” portion of FIG. 11, and FIG. 13 illustrates a state in which a circuit board is mounted on the circuit board mounting portion of the LCD shown in FIG. 9. For brevity, in the embodiments that follow, components having substantially the same function as the exemplary embodiment shown in FIGS. 1 through 8 are identified by the same reference numerals, and detailed descriptions thereof will be omitted or briefly given.

Referring to FIG. 9, in the LCD 2 according to a second exemplary embodiment of the present invention, an intermediate receiving container 100 includes a frame 120 on which a liquid crystal panel 37 rests, and a printed circuit board mounting portion 2000 positioned at an exterior surface of one of sidewalls 121 of the frame 120.

The printed circuit board mounting portion 2000 includes slide rails 2100 and 2200 into which the printed circuit board 34 is slidably inserted, a printed circuit board support portion 2300, and a stopper 2400.

Referring to FIGS. 10 and 11, slide rails 2100 and 2200 include upright portions 2110 and 2210 protruding from a first surface of a printed circuit board supporting portion 2300, and parallel portions 2120 and 2220 extending from the upright portions 2110 and 2210 in a plane that is parallel to the first surface of the printed circuit board supporting portion 2300. The upright portions 2110 and 2210, the parallel portions 2120 and 2220, and the first surface of the printed circuit board supporting portion 2300 form an insertion groove 2230 into which part of the printed circuit board 34 is slidably inserted.

The printed circuit board supporting portion 2300 supports the printed circuit board 34 inserted into the slide rails 2100 and 2200 to be mounted on the printed circuit board mounting portion 2000. The printed circuit board supporting portion 2300 protrudes from a sidewall 121 of the frame 120. The printed circuit board supporting portion 2300 may be formed to have a substantially similar outline as the printed circuit board 34. For example, if the printed circuit board 34 has a rectangular shape, the printed circuit board supporting portion 2300 may also have a rectangular shape. The printed circuit board supporting portion 2300 may be generally plate-shaped, for example. Meanwhile, the printed circuit board supporting portion 2300 may include an opening 2500 to enhance dissipation of heat generated by the printed circuit board 34.

The stopper 2400 protrudes from the sidewall 121 of the frame 120 and is disposed parallel to the printed circuit board supporting portion 2300. The stopper 2400 fixes the printed circuit board 34 inserted into the slide rails 2100 and 2200 on the printed circuit board mounting portion 2000. The stopper 2400 maybe made of an elastic materially.

Referring to FIGS. 11 and 12, the stopper 2400 may include a slanted surface 2410 that inclines downward with distance from the sidewall 121 of the frame 120, and a bottom portion 2420 that extends substantially perpendicularly to the sidewall 121 between an end of the slanted surface and the sidewall 121 of the frame 120. A gap G1 between the stopper 2400 and the printed circuit board supporting portion 2300 may be substantially equal to or slightly smaller than a thickness (‘t34’ of FIG. 13) of the printed circuit board 34 to be mounted on the printed circuit board mounting portion 2000.

Referring to FIG. 13, a first end 34-3 of the printed circuit board 34 is first slidably inserted into the slide rails 2100 and 2200. Thereafter, a second end 34-4 of the printed circuit board 34 slides along the oblique side 2410 of the stopper 2400 and is interposed between the bottom portion 2420 of the stopper 2400 and the printed circuit board supporting portion 2300 to be fixed by the stopper 2400. In such a manner, the printed circuit board 34 is mounted on the printed circuit board mounting portion 2000. Here, a rear surface 34-2 of the printed circuit board 34 is settled on one plane of the printed circuit board supporting portion 2300. In addition, a front surface 34-1 of the printed circuit board 34 is disposed to face the same side as a first surface 37-1 of the liquid crystal panel 37.

As described above, according to the current embodiment, the printed circuit board mounting portion 2000 and the intermediate receiving container 100 for mounting the printed circuit board 34 can be easily formed using a molded material. In addition, since a space for fixedly mounting the printed circuit board 34 is separately provided, additional processing time that would be required for fastening the printed circuit board 34 using fastening members such as nuts and bolts can be reduced in the manufacture of an LCD. This way, miniaturization of the printed circuit board 34 and higher integration density of the printed circuit board 34 may be achieved.

Next, a liquid crystal display according to still another exemplary embodiment of the present invention will be described in detail with reference to FIGS. 14 through 19. FIG. 14 illustrates an exploded perspective view of a third exemplary embodiment of a liquid crystal display (LCD) according to the present invention, FIG. 15 illustrates a circuit board mounting portion of the LCD shown in FIG. 14, FIG. 16 illustrates a cross-sectional view taken along the line IV-IV′ of FIG. 15, FIG. 17 illustrates a cross-sectional view taken along line III-III′ of FIG. 14, FIG. 18 illustrates a cross-sectional view taken along line IV-IV′ of a modified embodiment of FIG. 15, and FIG. 19 illustrates a cross-sectional view taken along the line III-III′ of a modified embodiment of FIG. 14. For brevity, in the embodiments that follow, components having substantially the same function as the exemplary embodiment shown in FIGS. 1 through 8 are identified by the same reference numerals, and detailed descriptions thereof will be omitted or abbreviated.

Referring to FIG. 14, the intermediate receiving container 100 of the LCD 3 according to still another exemplary embodiment of the present invention includes a frame 120 and a printed circuit board mounting portion 3000 positioned at one sidewall 121 of the frame 120.

Referring to FIGS. 14 and 15, the printed circuit board mounting portion 3000 includes a sidewall 121 that is partially cut out to form a recessed portion in the frame 120. The printed circuit board mounting portion 3000 includes a printed circuit board supporting portion 3100 on which the printed circuit board 34 is mounted, and mounting portion sidewalls 3200 and 3300 at the two ends of the recessed portion.

Referring to FIGS. 15 and 16, the sidewalls 3200 and 3300 include grooves 3210 and 3310 that extend across the width of the sidewall 121 of the frame 120 and into which the printed circuit board 34 is slidably inserted. The grooves 3210 and 3310 may be formed to penetrate through the one sidewall 121 of the frame 120. A length L3 of each of the grooves 3210 and 3310 may be substantially equal to a width (W1′ of FIG. 5B) of one side of the printed circuit board 34 to be inserted into the grooves 3210 and 3310. First and second ends of the printed circuit board 34 are slidably inserted into the grooves 3210 and 3310 and rest on the printed circuit board supporting portion 3100.

In the present embodiment, when the printed circuit board 34 is mounted on the printed circuit board mounting portion 3000, the printed circuit board 34 and the liquid crystal panel 37 may be substantially coplanar with respect to each other. Accordingly, in the present embodiment, the flexible printed circuit board 35 may not be bent or bent only minimally, thereby reducing a required length of the flexible printed circuit board 35.

Referring to FIGS. 14 and 17, in the LCD 3 of the present embodiment, the printed circuit board 34 connected to the liquid crystal panel 37 is mounted on the printed circuit board mounting portion 3000 of the intermediate receiving container 110.

According to the present embodiment, the printed circuit board 34 may be disposed at one side of the liquid crystal panel 37. Here, first and second ends of the printed circuit board 34 are slidably inserted into the grooves 3210 and 3310 of the sidewalls 3200 and 3300, so that a rear surface 34-2 of the printed circuit board 34 rests on the printed circuit board supporting portion 3100. In addition, a front surface 34-1 of the printed circuit board 34 may be disposed to face the same direction as a first surface 37-1 of the liquid crystal panel 37.

Referring to FIGS. 18 and 19, the printed circuit board mounting portion 3000 may include a securing portion 3212 formed on a sliding plane 3211 of the grooves 3210 and 3310 of the sidewalls 3200 and 3300. The securing portion 3212 may be shaped of a protrusion protruding from the sliding plane 3211 of the grooves 3210 and 3310 of the sidewalls 3200 and 3300. As described above, the securing portion 3212 may be received in a receiving part (e.g., 38 of FIG. 7) formed at one edge of the printed circuit board 34. Accordingly, the printed circuit board 34 is slidably inserted into the grooves 3210 and 3310 of the sidewalls 3200 and 3300 to then be tightly fixed. Therefore, when the printed circuit board 34 is mounted on the printed circuit board mounting portion 3000, a fastening force between the printed circuit board 34 and the grooves 3210 and 3310 may be increased.

Meanwhile, the securing portion 3212 may be a hook, and the receiving part (e.g., 38 of FIG. 7) may be a coupling hole (e.g., 38 of FIG. 7) penetrating through one edge of the printed circuit board 34. The hook may extend through the coupling hole, thereby establishing a connection between the securing portion 3212 and the receiving part (38 of FIG. 7).
